TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 482,524, datedSeptember 13, 1892.

Application filed May 31, 1892, Serial No. 434,884- (No model.)

To all whom it may concern.-

Be it known that I, LOUIS W. HASSENZAHL, of Toledo, county of Lucas, andState of Ohio, have invented certain new and useful Improvements inTemporary Binders; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form part of this speci fication.

Myinvention relates to temporary binders, and has for its object toconstruct a binder for the purpose of filing invoices, order-bills,receipts, and other memoranda in a convenient manner.

A further object is to provide for-simplicity of construction andconvenience in operation in inserting and removing papers from thebinder.

A further object is to provide for usingthe entire length of thefiling-pins for the reception of papers and means for securing theclamping-bar thereto.

lVith these objects in view the invention consists, broadly, in a back,filing-pins extending vertically therefrom, a coverand aclamping-barsecured thereto formed with perforations to receive the pins and acurved slot extending from the perforations to the edge, and acompressible substance upon the pins into which the clamping-bar mayimpinge to allow the cover to be secured at the extreme height of thepins, with means for preventing the ends of the clamping-bar fromassuming a horizontal plane when the coveris removed.

In the drawings, Figure 1 is a perspective View of the binder, showing anumber of papers filed therein. Fig. 2 is a rear edge view. Fig. 3 is arear edge view of the cover removed from the binder, showing the standards for limiting the movement of the clamping-bar. Fig. 4 is a likeview showing the standard upon the cover. Fig. 5 is an edge view of asection of the binder, showing the top raised and secured to thebinding-pins by reason of the clamping-bar impinging into thecompressible portion upon the bindingpins. Fig. 6 is an elevation of oneof the binding-pins, showing in cross-section a rubber band orcompressible portion into which the clamping-bar may impinge to allowthe same to vary the curvature sufficiently to permit the use of thebinding-pins to their extreme length and also to lock the cover when thebinder is filled, as well as to form a surface that will retard thepapers by frictional contact from accidental displacement when the coveris removed. Fig. 7 is an elevation of one of the binding-pins, showingthe compressible section inserted in one side only.

1 designates the back, flexibly connected with the end portion 2, inwhich are secured two vertical pins 3 of a height to receive the desirednumber of papers to be bound, said pins being providedwith acompressible section 4., preferably of rubber, either entirelyencircling the reduced end, as shown in Fig. 6, or inserted in one side,as shown in Fig. 7, the purpose of which is to allow the clamping-bar toimpinge into the compressible section and hold the cover when the binderis filled, and also to allow of utilizing the entire length of the pinsto hold the papers, as well as to form a retaining-surface for thepapers and prevent their accidental displacement.

5 designates the cover flexibly connected with an end portion 6, slottedtransversely at 7 coincidently with the filing-pins to allow the coverto be removed horizontally or inserted in the same manner.

8 designates a clamping-bar secured to the end portion 6'of the coverand engaging the pins. Clamping-bar 8 is formed with rearwardly-recedingrecesses 9, the openings of which are coincident with the filing-pins 3when the clamping-bar is curved, and a semicircular opening 10, themetal of which engages frictionally with the pins when the curvature isslightly decreased. At each end of the bar there are standards 11, whichare either joined integralwith the bar, as shown in Figs. 1, 2, and 3,or are formed separate and secured to the cover, as shown in Fig. 4, thestandards serving to limit the movement of the bar when the cover isremoved from the binder and cause each end to rest normally above theflat surface of the cover to allow of conveniently grasping the ends ofthe bar to replace the cover when adding new papers to the file. Thisfeature of my invention is of great value, as in the absence of thestandards the spring would normally lie fiat upon the cover and causeannoyance and delay, as well as injury to the fingers, in the act ofraising the same to cause the slots to coincide with the filing-pins.

It will be apparent that I may dispense with the standards and form thesprings with an upward curve, if desired, or I may secure any convenientattachment to the spring by which to raise the same, so that theapplication of power is above a horizontal plane parallel with thecover.

In the use of the binder when it is desired to refer to memoranda uponany of the pages the cover is raised and folded back. The tendency,however, is to close, due to the tension upon the end portion 6 by thepapersin the binder. I have overcome this objection by inserting aweight, as shown in dotted lines, Fig. 1, either of iron or lead, thateffectively holds the cover when opened.

In operation, when it is desired to file a paper the paper may be firstperforated in coincidence with the filing-pins, or the pins may becaused to puncture the paper. The top is then placed in position bycurving the clamping-bar to cause the slots therein to coincide with thepins, the slots 6 in the end portion 5 allowing the same to be placed inposition, when upon releasing the clampingbar the flexure of the springcauses the same to impinge upon the pins with sufficientforce to holdthe cover from vertical movement until released by curving the bar. Inorder to remove the cover, the bar is turned to cause the opening of thereceding slots to coincide with the pins, when the cover is movedhorizontally to withdraw the same and the bar from the pins. When thecover is removed, the standards formed upon the outer ends of the barcontact with the uppersurface of the cover and hold the bar sufficientlyraised at the ends to allow of conveniently grasping the same to replacethe cover. When the binding-pins are filled with papers to nearly theirheight, the bar impinges into the rubber at the top of the pins andallows of utilizing nearly the entire length of the pins, and when thebinder is full the impingement of the bar into the rubber locks thecover sufficiently to effectually hold the same in place. I

It will be seen that I have provided an inexpensive and compact bindercapable of being easily operated to receive additional papers and thatwill securely bind those 1nclosed therein.

What I claim is 1. In a binder, the combination, with a back, of thefiling-pins secured thereto, a cover formed with slots adapted toreceive the pins, and an upwardly-curved clamping-bar secured to thecover centrally between the pins, said bar having slots near its outerends to receive the pins, and said bar normally binding upon the pinsand holding the cover in position.

2. In a binder, the combination, with a back, of the filing-pins, thecover, the clamping-bar secured to the cover and adapted to engage thepins, and the supports for elevating the ends of the clamping-bar.

-3. In a binder, a back, a cover, a clampingbar secured upon the cover,clamping-pins secured to the back and havinga compressible section atthe upper ends.

4. In a binder, a back formed with flexiblyconnected end portions,filing-pins secured in the end portions, a cover having aflexiblyconnected end portion having slots coincident with thefiling-pins, a clamping-bar secured upon the end portion of the covercentrally of the pins and formed with recesses to receive thefiling-pins, and a weight upon the opposite end of the cover.

In testimony that I claim the foregoing as my own I hereby affix mysignature in presence of two witnesses.

LOUIS IV. HASSENZAHL.
